Errr, DB, how do you even calculate this one?

Public transport in Luxembourg is FREE

And Troisvierges and Luxembourg are both, errr, in Luxembourg 🤯

@jon pretty sure the only ticket the DB knows about for this is the Saar-Lor-Lux ticket (a ticket obscure enough the Wikipedia page still prices it in Marks) and is simply not aware of the “ticket” known as free travel

@q @jon This makes me think that Luxembourg should actually issue a 0 € ticket so that journey planners can calculate the total cost of travelling via Luxembourg.

Could anyone point me to the standard (I hope there is one) for expressing ticket validity digitally please?
